The battery is the heart of your electric bike. Proper maintenance will help you maximize its lifespan. Here are some tips to take good care of your e-bike battery.

Key takeaways:

  • Manage charging carefully: recharge before the battery drops below 20–30%, avoid keeping it constantly at 100%, and always use the original charger.

  • Optimal storage: keep the battery at around 40% charge, in a dry, cool, and temperate place.

  • Recharge your battery regularly, even if you’re not using your bike.

  • Monitor any loss of performance and make sure to repair or properly recycle damaged batteries.

Managing your battery’s charge

Good charge management is essential to preserve your battery’s range and overall health. Below are our Doctibike experts’ recommendations.

  • During the first five uses, fully charge and discharge the battery.

  • When charging, plug the charger into the wall socket before connecting it to the battery. Why? Plugging the charger into the wall may create an electrical arc. While chargers are designed to withstand this, batteries are not.

  • Never let the battery discharge completely. Recharge it before it drops under 20–30%. Avoid keeping it fully charged at 100% all the time to preserve its lifespan.

  • Remember to charge your battery regularly, even if you don’t use your bike (at least once per month). This helps avoid deep discharge, which occurs when a battery is left fully depleted for too long. This can damage cells, reduce range, or even prevent the battery from functioning.

  • Handle the battery carefully and avoid impacts. If it suffers a major shock or shows signs of oxidation, bring it to a recycling point or a Batribox/Ecosystem drop-off station.

  • Use the original charger provided by the manufacturer to ensure stable charging and avoid surges or micro-faults that could damage the battery or cause thermal issues. If you need a replacement, choose a compatible charger.

How to store your battery

During long periods of inactivity, the ideal charge level for storage is around 40%, to reduce self-discharge. A battery stored at 100% may self-discharge up to 20% more compared to one stored at 40%, depending on temperature.

Store your battery in a dry and cool place, away from major temperature variations. Excess heat can accelerate cell degradation, while extreme cold reduces performance. Moisture can cause corrosion and weaken electronic protection. Ideally, keep the battery in a ventilated room at a stable temperature, away from heat sources (radiators, sun) and cold (unheated garage).
